Periods every 2 weeks

[givemecrisps]

Currently a 33 year old mum to a 1 year old and a 6 month old. On cerrazette for birth control but I've now gone from have ridiculously heavy bleeding all the time to, 2 normal periods a month, with the delightfully debilitating migraine to go with it. Has anyone had anything similar and there periods have settled back down?
I've had tests at the doctors and all is apparently healthy.

It will be the mini pill as it can cause erratic bleeding. Are you breastfeeding and that's why you're using cerazette?

No I am very prone to migraines so struggle with most other contraception. Before my children I have the injection for 5 years but didn't realise how much it affected my moods until I came off it. I've also unsuccessfully had the implant as it gave me constant bleeding and bad anaemia
